DESCRIPTION :

GRAVIS I & GRAVIS II

The goal of this project was to create a versatile product that can be perfectly integrated into every living environment, ideally matched not only with Sonus faber’s new Sonetto family, but also with almost every kind of music and video system.

Gravis I, a formidable solution for people wanting accurate bass extension for middle sized listening rooms; it’s a powerful medium sized subwoofer package representing an ideal compromise between size and performance. It features a down-firing 8” active driver, along with a high current 150W Class AB amplifier allowing it accurate and expressive bass reproduction well beyond its class.

Gravis II, a fitting choice for more demanding audio systems, it represents design synergy at the highest level. It features a front firing 10” passive radiator with a down-firing 10” active unit, along with a high current 400W Class AB amp. The combination of a larger cabinet, perfectly tuned to the larger driver compliment and 400 watts of refined power provides excellent bass extension with the speed, impact and nuance required to underpin the most engaging music and theater systems.

 

 For both Gravis I and Gravis II the preamp stage is a highly advanced design specifically developed for this application; it is responsible for the texture, speed, and attack of these two “small” subwoofer models.

Moreover, Gravis I & Gravis II’s rear panel features a complete connectivity solution that allows for both perfectly blended musical sub bass and powerful, percussive, home theater bass. A wide sound field reproduction is the result whenever this subwoofer unit is matched with a loudspeaker system. It’s sound is rock-solid, fast and has startling depth.

The separate volume controls for High Level and line/LFE allow perfect calibration for music and home theater so there is no need to make any adjustments between sessions in dual-use systems. In fact, while the High-Level Connection allows seamless blend of the sub with the main speakers in music reproduction, the LFE input can be used along with it to provide an immersive home theater experience simultaneously.

For over three decades, driver design has remained one of the most important factors of Sonus faber’s loudspeaker systems. In fact 100% of the company’s current product line features drivers that are designed and developed at its laboratories in Vicenza, Italy. From this rich knowledge pool emerges the care and attention required to design and produce relatively small driver units that provide truly low bass and are able to withstand high power and output for long periods of time.

Both Sonus faber Gravis I & II use quality stamped steel-frame speaker units: the Gravis I features a 8” Ultra Long Throw down-firing speaker unit and the Gravis II uses a 10” Ultra Long Throw down-firing speaker unit and a 10” aluminum alloy diaphragm passive infra-bass radiator.
